Biography
After her brother ran away from home in Pagai, Phryne, Brother's Keeper set out to find him once she had enough drachmae to live on her own. The war pushed her into many situations she didn't expect, but she persisted. However, there was no record of her ever having a sibling. In 431 BC, she was sent to hunt down and kill Kassandra on Keos, but Kassandra slew her after a short battle.
